Collapsing Buildings

The New Phenomenon of Steel Buildings Crushing Themselves

The seven World Trade Center buildings were in the two blue regions
of the map to the right.
On September 11th,
all 7 buildings were destroyed.
110-story
WTC 1 and
2, and
47-story WTC 7
were leveled, and
WTC 3,
4,
5, and
6
were severely damaged, with large portions of
WTC 3, 4, and 6 being crushed.

It is interesting that,
in spite of the thorough devastation of all the buildings
with World Trade Center addresses, no large buildings outside the blue zones
were sufficiently damaged to warrant their demolition
in the months that followed the attack.

The "collapse" of Building 7 was remarkably tidy.
Although it was wedged between the Verizon building
and the U.S. Post Office building, it barely damaged either of them.

It is even more interesting that,
prior to September 11th,
no steel framed building had ever undergone total collapse due
to any cause or combination of causes
other than controlled demolition and severe earthquakes.
Such buildings have survived hurricanes,
severe fires,
earthquakes,
and bombings,
but none have fallen down of their own weight --
an event that was
portrayed as inevitable
on September 11th.

Of the collapses of the three huge buildings on September 11th,
the collapse of Building 7
is treated separately.
If you believe the official story, then Building 7 would be the
only example in history of a steel framed building undergoing
complete collapse as a result of fires.
It and the Twin Towers would be
the only permanent vertical steel structures
to have fallen into themselves instead of falling over,
except in cases of demolition.

The collapses of the Twin Towers
are analyzed in much more detail than Building 7
because there is more evidence,
and because,
whereas Building 7's fall looked like a standard building demolition,
the disintegrations of the Twin Towers had many
features
that are not easily explained.
